Hello Jacek,

I believe the Qt layer of ROOT was compiled and built against of 3.3.2  (in other words against of CERN-LCG default version as seen on afs  /afs/ )


 It says,
" . . .
  Qt Improvements

 We found Qt 3.1 is too buggy to support the functionality ROOT needs.  See:

You are advised to install the fresh version, which Qt 3.3.4 at the moment. It should be binary compatible with the ROOT distribution.

The recommended flags to install the Qt are

./configure -thread -no-xft -qt-gif -no-exceptions

I've found the tml

claims to be built against Qt 3.3.

I do not know whether this "rpm" is sufficient to bring the Qt 3.3 up.

Best regards
